This BHA blackhead power liquid contains 4 percent natural BHA. It contains natural BHA component of betaine salicylate that maximizes exfoliating and clearing benefits without irritation. Willow bark extract and niacinamide brighten skin with gentle exfoliation while sodium hyaluronate boosts hydration. BHA penetrates deeply into the pores and helps to clear clogged pores and gently exfoliates dead skin cells, giving the skin its natural glow. It helps to get rid of blackheads and sebum inside of the pores but also prevents sebum from turning into blackheads via oxidation.
